Resilient window stop



July 7, 1925.

E. J. PLAYFOOT RESILIENT WINDOW STOP Filed Nove 4, 1924 i "i" 'l I i `Application filed sN'o'vervriber 4, fserial-V 7471808 "l e" causing the sashes to frictionally hold at any point to which they are shifted, and the object of the invention is to provide a device of this character including a springsupported roller mounted upon one window sash and bearing against the other window sash.

A further object in this connection is to provide a very simple, cheap and easily applied device of this character which will not only hold the lsashes in their adjusted positions but hold the sashes tight against the stop so as to prevent the entrance of air and prevent the sashes from rattling.

A still furt-her object is to provide in connection with a roller stop of this character means for latching the sash upon which the stop is mounted from upward movement when the sash is lowered.

Other objects will appear in the course of the following description.

lMy invention is illustrated in the accompanying drawing, wherein Figure 1 is a perspective view of a portion of a window and its casing showing the application of my device thereto;

Figure 2 is a sectional view through the window casing showing the bolt holding the casing closed.

Referring to this drawing, A designates the lower sash, B the upper sash, and C thel frame of the window. These sashes are constructed as is usual. My roller stop comprises a supporting bracket formed of a relatively heavy resilient wire. kThisis so formed as to provide a looped portion 10 adapted to rest upon the meeting rail of the lower sash, a portion 11 which extends downward and bears against the outer face of one side sash rail, a portion 12 which extends upward in an inward curve, and a cross bar 13 carried by the portion 12 at its upper end and upon which is mounted a vroller 14. I

have illustrated the supporting means for Patented July 7,1925. y t di nnwaana., rLAYFooT, or cameron; PENNSYLVANIA.

the roller 14;r v.as =being cin'npos-ed,V of two strand'ysofjwire, but itf'will be understood, that any other arrangementof this` characte'r might be iliade and ac'hievelthe same result, though preferably wire is used as being the cheapest material.

Preferably the face of the window is slightly groovedto receive the two sides of the portion 10, and a cap plate 15 may be disposed over the upper end of this side rail of the window sash and clamped down so as tohold'the bracket in place. Preferably, though not necessarily, the side rail is formed with anl opening 16 facing the window j amb. Disposed within this opening is the sash bolt 17 which may be Vprojected by a spring into an opening 18 in the window jamb and which is retracted by means of a pin or stud 19 connected to the bolt and extending upward through a slot 20 in the plate 15. n.

It will be seen that this device when placed upon a lower window sash, as above explained, causes the roller to bear against the upper window sash to a degree which will force this upper window sash against its appropriate stops and prevent any rattling of the upper window sash. The same forcewhich urges the roller up against the upper sash will cause the lower sash to be urged inward or against its stop. Thus the two sashes will be. held from rattling and either sash may be raised or shifted and held by the frictionalengagement of the roller with the window sash B against any accidental movement when the window sash A is lowered to its full extent. The bolt will project into the keeper formed in the jamb and thus the lower sash will bev locked against upward movement until the keeper is withdrawn.

Vhile I have illustrated certain details of construction and arrangement of parts, I do not wish to be limited thereto as it is obvious that these may bechanged in minor respects without departing from the spirit of the invention as defined in the appended claims'.

I claim scribed comprising a supporting member 'having a horizontal portion adapted to rest upon the upper face of the lower window sash, a vertical portion tol extend down against the face of the lower sash and a portion extending upward from the lower end of said vertical portion to a point above the horizontal portion and then inward, this last named portion being resilient, and a roller carried upon the upper end of the Vlast named portion and adapted to'bear against the upper sash to thereby resiliently urge the upper and lower sashes apart.

2. A device of the character described Comprising a supporting member formed of an elongated wire loop, the wire loop at one end being bent to forln a horizontal portion adapted to rest upon the upper face of a lower sash, a vertical portion adapted to rest against the outer face of the sash and afportion extending upward and outward and then inward from the lower end of said vertical portion and carrying at its upper end a roller, said last named portion of the supporting member being resilient to thereby urge the roller inward against the face of the upper sash to thereby hold the sashes yieldingly urged apart.

In testimony whereof I hereunto afIiXf my signature.
